Nabbed!
In all honesty, Pickham's Casino is a waste of time. The slots don't pay out enough to be worthwhile and Bingo has no RNG to it at all - the same boards will give the same results every single time. But even if you do earn a decent amount of tokens by abusing the latter fact, the mediocre prizes just aren't worth the effort.
That said, I did, so I decided to make the best of it. I purchased a Rune Staff for Jessica, two Silver Platters (which can be crafted into White Shields when combined with Iron Shields) and one Agility Ring (which can be combined with a Bandana into a Mercury's Bandana); I'll have to wait until after I get Medea and the cart back before I can do all that, though. I had about 5000 tokens left over which I'll save for the much better casino later on.
